#451 moved every editor gesture onto the live painter, and the guides stayed behind in the settled scene. While a gesture runs, the settled scene is not re-rendered at all, so the guides did not follow the marker in the device editor, the shape in the backdrop editor, or the cursor while a contour is drawn in the plan editor. Measured with real pointer events on the demo stand against `origin/dev`, after waiting for the editor chrome to settle: three gestures, each exactly on another object's axis, 0 settled render cycles, `.alignline` 0 and no `.alignguides` group in all three. The report called it two breaks. It is one — the layer — plus one thing that would have broken the repair: `_alignPoint` read `_pos`, which during a live gesture answers from the snapshot of the last settled render. Over one drag: live 254.17 → 220.83 while `_pos` stayed at 254.17, eight grid steps behind, so a restored layer would have drawn the guide at the marker's old place. The live template now paints the guides in all three modes (the device editor had no template at all — `paintDevice` only moves the marker element), and `_alignPoint` takes the live position. The settled copy of `.hp-editor-only-layer` is made transparent for the duration of any editor gesture, not only in plan mode: two guides, one of them stale, is what the user would otherwise see when an unrelated settled render lands mid-gesture. `_renderAlignGuides` on the card becomes soft — a gesture that starts while the editor runtime is still loading must cost nothing, and an exception inside a `requestAnimationFrame` paint would take the whole gesture with it. The witness is rewritten around the defect that hid this for two stable releases: the old smoke assigned `_deviceDrag`/`_decorDraft` wholesale, and an assignment with `oldValue == null` does not route to the live path — it verified a state a real gesture never reaches. Every scenario now drives real `PointerEvent`s, waits for silence first (the `_hdrH` settling window right after entering a mode hands out settled frames that make even the broken code draw a guide), and asserts zero settled cycles during the movements plus exactly one `.alignguides` group. #400's exclusion is checked without touching the drag state: the dragged marker must simply be absent from the candidates. On `origin/dev` the smoke fails on nine of its facts; a witness that stays green before the fix was the actual bug here. Mutants: `live-editor-devices-drops-align-guides`, `live-editor-decor-drops-align-guides`, `live-editor-plan-drops-align-guides`, `align-point-reads-frozen-snapshot` — one per AC, all guarded by the smoke. `test/smoke-harness-contract.test.mjs` pins that the smoke cannot go back to fabricating gesture state.

🏠 House Plan — a live home map for Home Assistant
📘 Full user guide · 🇷🇺 Русский · 🗂 Project issues
Your whole home at a glance
House Plan turns Home Assistant into a live map of your home. Open the dedicated House Plan item in the Home Assistant sidebar, upload a plan or draw rooms, bind them to Home Assistant areas, and the area's devices appear automatically. You can immediately see where a light is on, a door is open, a room is too cold, Zigbee signal is weak, or a leak sensor has fired.
Setup is entirely graphical: no floor-plan YAML, Inkscape, or external editor. Plan data and device positions live on the Home Assistant server and stay in sync across screens.
Edit on a desktop computer. View and kiosk are fully supported on phones and tablets. The editors are designed primarily for a mouse and keyboard; individual touch editing operations may be awkward or unavailable. See the exact touch support contract.
What House Plan provides
- Live state and safe actions. Lights and other safe devices can toggle from the plan; a lock cannot be opened by an accidental plan tap.
- Three built-in editors. Plan creates rooms, walls and openings; Device places and configures markers; Background adds lines, labels and furniture.
- Area-aware rooms. New devices appear automatically, while room cards can show temperature, humidity, light state and average LQI.
- Light and environment. Room fills, lamp Glow, wall shadows, a day-cycle backdrop and sunlight through windows.
- Doors, windows, gates and vacuums. Openings follow real contacts and locks; a robot can show its position, dock and travelled path.
- Several floors and screens. Space tabs, swipe navigation, local viewport, and a separate initial floor for each card.
- Wall-display kiosk. A plan-only view with fullscreen navigation and icon sizes saved for that display.
Your first working room
- Install the integration and open House Plan in the Home Assistant sidebar.
- Create the first space: upload SVG/PNG/JPG/WebP, reuse an uploaded image, or choose no image and draw the plan by hand.
- In Plan, select Room outline, place vertices, and click the first point to close the outline.
- Name the room and bind it to a Home Assistant area. Use “No area” for a room that has no devices.
- Open Device: devices from the bound area are already placed; drag their markers to the correct positions.
- Optionally use Background for lines, text and furniture.
- Return to View. The plan now displays live state and accepts safe actions.
Every workflow and edge case is in the full user guide. The Background editor contract and vacuum guide are the authorities for those subsystems.
Installation
HACS
House Plan is in the HACS default catalog — no custom repository needed.
- In HACS search for House Plan and install it.
- Restart Home Assistant.
- Open Settings → Devices & services → Add integration → House Plan.
The sidebar page and optional dashboard cards are registered automatically.
After installing or updating House Plan,
restart Home Assistant and fully reload the page: Ctrl+F5 on Windows/Linux or
Cmd+Shift+R on macOS.
Storage mode (Home Assistant default)
No YAML is normally needed. If automatic registration did not make the card
available, open Settings → Dashboards → menu ⋮ → Resources → Add
resource, enter /houseplan_files/houseplan-card.js, and select JavaScript
module.
YAML resources mode (Home Assistant 2026.2+)
To manage resources in configuration.yaml independently of the dashboard
mode, use:
lovelace:
resource_mode: yaml
resources:
- url: /houseplan_files/houseplan-card.js
type: module
Legacy Home Assistant 2024.6–2026.1
Only for a full-YAML dashboard that is already managed in YAML, use:
lovelace:
mode: yaml
resources:
- url: /houseplan_files/houseplan-card.js
type: module
mode: yaml changes the dashboard itself to YAML mode. Do not switch a storage
dashboard to legacy YAML just for House Plan; use the Storage mode instructions
above instead. Do not use the on-disk path inside custom_components; Home
Assistant does not serve that path as a JavaScript module.
Manual installation
Copy the complete custom_components/houseplan release folder to
config/custom_components, restart Home Assistant, and add the House Plan
integration. Do not copy only houseplan-card.js: the card also uses an
internal manifest and content-hashed modules from the same release.
Open House Plan
After the integration is added, open House Plan in the Home Assistant sidebar. This full-page view is the primary entry point and needs no dashboard or YAML setup. It remembers the last space but always returns from another HA page in View rather than reopening an editor. Users without editing permission see the same live plan without editor controls.
If the sidebar entry cannot be registered, the integration and existing dashboard cards continue to work; check Settings → System → Repairs → System information → House Plan after restarting and hard-refreshing HA.
Optional dashboard card
Add the card only when House Plan must be embedded in a dashboard. In a Sections view it requests full width by default, while a manual size chosen in HA remains authoritative. Add it in the UI or as:
type: custom:houseplan-card
title: House plan
Different screens may start on different spaces:
type: custom:houseplan-card
default_floor: ground
All cards share server-side rooms and coordinates. Current mode, viewport and selected space remain local to the screen. Revision checks and live sync cover concurrent clients, but avoid editing the same object in two browsers at once.
